(01. 277-52) My invention relates to the art of burning pulshaft 32 within housing In is an arm 38 which is verized fuel and more particularly to means for secured to the shaft by means of a key 40 and distributing pulverized fuel among a plurality of a set screw 42. A pair of sleeves 44 may be burners. mounted on shaft 32 between arm 38 and the My invention relates to a distributing valve sides of housing H! in order to substantially 5- whereby a mixture of pulverized fuel and air prevent lateral movement of the shaft.

on the outer periphery of this rim the stream of powdered fuel passing through the opening 22 into left hand conduit 38 will not pass in contact,

with the left hand seat. Hence the valve face seat will not be worn by the abrasive action of the powdered fuel.

If it is desired to Supply 'powdered fuel to both 7 of the conduits 38, chain 62, which extends to in such a manner as to rotate wheel 68 soas to rotate shaft 32 in-a clockwise direction. as viewed in Fig. 1. This causes valve member 46 to move to the position shown by the dash-and-dot lines in Fig. l and causes arm 64 to move to a vertical position as shown by dash-and-dot lines: Arm 64strikes the resilient member I2 and is retained in the recess formed at I4 and is thus hel d in a In this position valve member 46 is behind wedge-shapedmember I6 in the line of flow-which protects it from the stream of powdered fuel and'air which is admitted into housing I8 through inlet opening I2'and' is thereby protected from abrasive action of the powdered fuel. r a

If 'it is desired to admitpowdered fuel to the right hand conduit 38"only, wheel 68 is further rotated so that valve member 46 will be rotated 50 as to closethe opening inclosure member 28 which communicates with the left hand conduit 38. Valve member 46 will be held in this position by means of counter-weight 56 on arm 64 which will now be in a substantially horizontal position but on the opposite side from the position shown in Fig. 1.

The form of distributing valve shown in Figs. Band 4'is so constructed that both of the .conduits 38 may be closed at the same time. This form comprises a housing I8 provided with an insure member 28 is provided with a pair of outlet openings 22 which communicate with the conduits 38. Openings 22 are surrounded by raised rims 24 onthe outer periphery of which are I82 of a valvemember I84.

formed valve face seats. 7 Secured'to the inner central portion of closure member 28 is a bearing 88 in which are journalled the inner ends of a pair of shafts 82 and 84. V

Shaft 82 extends through a bushing 86 screwed into a boss 88 formed on the outside of housing I8, while shaft 84 extends through a similar bushing 98 screwed into a boss ,92 formed on the other side of housing I8. Secured to theouter end of shaft 82 is an arm 94 which carries a counterweight 96, while an arm 98 provided with a counter-weight I88 is secured to the outer end of shaft 84. v I

Keyed 'to the inner end of shaft 82 is one arm of the valve member is loosely Journalled on a shaft 84. Keyed to the inner end of shaft 84 is one arm I88 of a valve member II8, while the Another arm I86' other arm II2 of this valve member is loosely journalled on shaft 82.

Each of the valve members I84 and H8 is provided with a cone-shaped valve face II4 which fits the valve face seats formed on rims 24. Se-

cured within housing I8 near the inlet I2 thereof is a wedge-shaped member II6 provided with an inner extension H8 which serves'as a stop for valve members I84 and H8 when they are'in open position.

Secured to the outer side of closure member 22 directly above shaft 82 is a member I28 to which is pivoted a latch member I22. A similar member I24 provided with a latch I26 is secured to 010-.

sure member 22' directly above shaft 84.

The above described device operates as follows:

If it is desired to admit powdered fuel to the righthand conduit 38 only, the valve is placed in the position shown in Fig. 3. valve member I84 is in a substantially vertical position behind wedge-shaped member I I6. -Arm 94 carrying'counter-weight 96 is likewise in'a vertical position where it is retained by latch I22.

Valve member l I8 is in closed position with its face I I4 in contact with the valve seat face formed on rim'24 around outlet opening 22 which communicates with the left hand conduit 38. Valve member I I8 is held in this position by the action of counter-weight I88 on arm 98 which is keyed to shaft 84. r I

If it is desired to supply powdered fuel to both of the conduits 38, arm 98 is rotated to a vertical position where it will be retained by latch I26,

which may be raised by hand to allow the arm to take-a vertical position and then lowered so as to embrace the arm and retain it in this position;

If it is desired to closeboth of the conduits, latch I22 engaging arm 94 is raised and the arm rotated so as to bring'valve member I84 in closing position withrelation to'outlet opening'22. The valve member will be held in this position by the action of counter-weight 96. i

In this position Thus it'will be seen thatI have provided asimple and sturdyform of distributing valve, thefaces of which; valve are not subject to wear by the abrasive action of the fuel stream passing'through the valve, inasmuch'as these faces are kept out While I have described two more or less specific forms of my. invention, it is to be understood that changes, additions or omissions which are apparrent to one skilled in the art fall within the scope of my invention, which is to be limited only by the breadth of the appended'claims.
